One of the houses across the road from me is having some building work carried out.
Earlier I was looking out the window to see what was the cause of some loud talking I could hear (it was just some neighbours shouting to each other), when I noticed a very well-behaved, large, white dog, sitting next to the builders van and piles of materials.
"Oh, what a well-behaved, dog" I thought to myself.
But then, about an hour later, I noticed it was still sitting there.
Upon much closer inspection (I had to go outside for a look) I discovered it was actually just a large white 'rubble bag' of that sort-of fabric variety, with the top gathered around into a bunch, which was moving ever so slightly if the wind blew, which gave it the impression of animation.
